Directional weighted spatial fuzzy C-means for segmentation of brain MRI images

The authors identified errors in this recently published paper [1] and would like to make following two changes.

1. Original title of this paper does not accurately reflect this work. A new title should be “A spatial fuzzy C-means algorithm for segmentation of brain MRI images.”

2. There are errors in the reported segmentation accuracy data of the proposed framework with brain in Table 2. The corrected Table 2 is shown in the following.
